Well it is a one and done episode. The Trial of the Flash has been concluded.

The evidence is stacked against Barry. heavily.

An attempt to discredit Devoe's wife's testimony was anticipated and stopped.

Team Flash must stop a radioactive meta named Fallout from going nuclear.

Barry is found guilty and sentenced to life without parole, just like his father. He even gets the same cell his father had as written on the wall "henry allen was here"

Devoe taunts barry and reveals that he now has his host body's mind reading power as well as his super intelligence and that Barry cannot comprehend the long game that Devoe is playing.

Devoe does seem slightly taken aback in his chat with Barry at something Barry is thinking as Barry vows to beat the rap and come for Devoe

Barry also actively stops Iris from telling the court that he is the Flash. Barry refuses to out himself due to endangering Iris and his friends. (man I am sick of that tired old trope)

Also Barry appears to be in gen.-pop. in prison, not good for a now former cop.

Still, despite being in prison Barry can use his powers to keep himself safe. Also since he can phase through walls, he has his own get out of jail free card as it were so anytime a meta emerges that the rest of the Team Flash can't handle Barry will slip out of prison and be back before he is missed.

Also there is one way Barry can beat this, but he won't do it. He could always slip out of prison and do the one thing that he should not do, the one thing that Devoe may not anticipate or be able to prepare for.........Barry could do the TIME WARP AGAIN and go back a few months to the day he escaped the speed force and stop Devoe.

Or perhaps in an ironic twist the Reverse Flash will assist Barry.

That would be supreme orony, to have his greates enemy, RF,help Barry out!
